GAS-IRON.

To all 'uihom it may concern: 7

' Be it known that I, HARRY A. Konme, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Gas-Irons, of which'the following is a s )ecification.

ome of the objects of the present invention are to provide a gas iron wherein the ironing surface is maintained uniformly heated; to provide means to preventback firing and choking of the flame due to currents of air produced when the iron 1s in use; to provide means to maintain. an even predetermined circulation of the heated products;

to provide means for carrying off the waste products without permitting a1r to enter the ironbody byway of the exhaust vents; and to provideo'ther improvements as Wlll I hereinafter appear.

In the accompanying drawings ljigure 1 represents a side elevation of a gas ironembodying one form of the present lnvention; Fig. 2 represents a top plan of the same; F g. 3 represents a transverse section on line 3 -3 of Fig. 1; Fig. 4 represents a top plan of the hollow body part of the iron; and Fig. 5 representsa plan of the device for forming air passages and shielding the-handle portion from the discharged 7 products of combustion. I

Referring to the, drawings one form of the present invention is. shown wherein a body 10 is provided which preferably contop casing 12 arranged to be removably secured to the base 11 thereby forming in assembled condition a chamber 13. The base 11 in the preferred form is substantially elliptical providing oppositely pointed ends 14, and having'a flat finished bottom face 15 for the usual ironing purpose.

' For'removablysecuring the casing 12 to the base 11 a plurality of machine screws 16 through openings 17' respectively in the .casing 12 and havescrew-threaded-engagement with the base 11, so that in operation the two parts of the body are fixedly secured together. V V

In order to heat the bodylO and particularly the base 11 and the ironing face 15 thereof, the casing 1.2 is cut away or recessed at the rear end to receive a. burner 18 of any suitable form but preferably of the Bunsen Specification of Letters Patent. Application filed 'A fii' s,

p nta; June 28, 1921; 1919. Serial no. 288,486. I M i upon the base 11 th'e'burner 18 is arranged to. direct the flame into a main' combustion chamber 23 formed by a deflector 24 which isremovably securedto the casing,,12. In the present instance this deflector 24 is pro-1 vided with side flanges 25 arranged to seat on the base 11 and having openings 26 at suitable intervalswalongfthe edges to permit the products of combustion to pass laterally into the chamber 13. i i

In. order to promote combustion effectively a the casing 11' is provided with a plurality of air inlets or passages .27 arranged along the bottom circumferential edge of the casing 11 to form communication between the chamber 13 and the exterior of the body 10; These inlets 27 introduce air in close prox imity to the discharge opening or openings in the deflector 24 so that complete combustion takes place and the desired blue heating flame is maintained. a

As a means for securing a uniform circus I lation of the heated products within thebody 10, and also preventing choking or smothermg of the flame when the ironis in use, the

inner wall30 of the casing 11 curves -inwardly and upwardly from the floorof {the base 11 at each side in a relatively long uniform sweeping curve with its highest por-. tion substantially coincident with the line of intersection between the casing 12 and the vertical longitudinal axial planeof the body 10. At opposite sides ofthis plane the cas ing 12 is provided respectively with two series of relativelylarge,vents 31, arranged substantially in alinement longitudinally of the casing 12 while betweentheseseries. of vents are aplurality of smallerloutlets32 so located as to release. products which pass to the highest portion of the chamber 13. v

To further promote combustion and'produce an artificial draft aplate 33 is provided consisting of a pairof laterally disposed, elongated concave wings 34 which are connected together by a strip 35 interposed between them and arranged to be fixed in I place upon the body '10 by screws 36 or other fastening devices. Preferably these screws 36 also serve to hold the handle 37 by which the iron is manipulatedin use.

These Wings 34: in operative position have their respective concave portions juxtaposed v with respect to the outer top surface of the casing 12 but spaced therefrom a suitable distance to form channels 40 extending longitudinally o f the sea body 10. This spacingi's effected by the provision of upstanding lugs 41so that inassembled conditi'onjthere is a free air space between the the strip 35 it is evident that all the displate 33 and the casing top, which {space takes the form time parallel channels disposedf respectivelyfabove the two series of ventsi As the outlets 32' discharge beneath charged products of combustion enter the space beneath the plate"33 and V are then carried longitudinally of. the body and dissipated.

' In the roperation of the iron the flame from, theburner 18 is projected within the chamber 23 where it is fed by air entering by w'ay'of'the passages 27 and j'to support combustion while the products pass outwardly through the openings25 and pass upwardly, being directed by thev curved walls to the main vents 31 and supplemental outlets 32.- As the iron'is reciprocated in use currents of air passfirst in one direction and-thenlin the other'through the channels 4Q and perform the double function of drawing out-the products from the casing 12 and keepingthe plate 33 cool. Thefunction of maintaining a'circulation of the products is an important "one andit is'desirable to defi-- nitely proportion the size and numbers of the vents 31 and 32 with respect to the area of theft channels 40 because too many or too "large vents result in the too rapid withdrawal" of the products which directly aifects 'the efiiciency of the iron,

while too 'few vents chokes the combustion. By the present invention the flame is notsubj ected' toair' currents tending to force it laterally through the air.- inlets and thus burn articles beingironed, and this is true irrespective of the "direction of movement of V the iron, "Itwill further be evident that the outlet vents 'for the 'wastenproducts are arranged to all'discharge theproducts trans 7 be'inserted for starting the burner.

ve'rsely'to the peace the moving currents of air and in consequence they are carried away instead of being forced back into the combustion'chamber. Since in the preferred form the body comprises two separable partsfitis desirable to provide meansfor lighting the burner withoutopening the casing and to that end one oftheair inlets adjacentto' the rearfofthe body is enlarged s'ufiiciently to permit a match or the like to 7 This opening is indicated at 42; While but one form of the invention has been shown by way ofexample itwill be understood that the same'is not limited to'the exact construc- "tion" shown as various modifications may be made without'departing from the invention.

It will now be apparent that thepr esent invention provides a free uniform fiame which'is unaffected by currents of air in the operation of the iron, and wherein .the air acts in a predetermined 'manner to assist and promote the circulation ofthe products so that any tendency tochoke, the fiame isoven come. o

Having now described my inventionwhat.
